Tile & Floor Care Nano Boost is developed using the latest Nano-technology. It is perfectly suited to treat nano sealed tiles and other hard, low porosity tiles. Nano Boost is an impregnating sealer and therefore lives inside the tile. Nano Boost will not change the natural look and features of the tile. What you see is what you get except now with extra protection. As Nano Boost live within the tile it offers a long life span. Nano Boost is a breathable sealer i.e. it allows vapor transmission through the tile and will therefore not lift or peel.
